Most of the animal stock is mainly fed on farms and homestead plots. Farmers grow the fodder crops required for the stock (corn, clover) on their land plots of 0.5–3 hectares. Technological operations, particularly mowing of crops, are made manually in such small areas as the operational quality of traditional mowing units used on small fi elds is far from good; moreover, they may damage crops and consume plenty of fuel, which may increase costs and cause fi nancial losses to farmers. The operation of mini-grass mowing units can help avoid such nuisances. This needs a rationale for the operating parameters of small units. Rational working rate and working width of a small mower comprising a mini tractor TTZ-30C and a mini mowing unit KOS2,1 the basic methodologies of tractor dynamics and composition of machine-tractor aggregates (calculation of power balance, determination of traction resistance of the unit) have been used for justifying the parameters. An investigation of the power balance has defi ned numerical values for the hook capacity (4,06 kW) and traction resistance (1,195 kN) of a grass mowing unit. A working width of 2.1 m and a rational working speed of 12.23 km/h correspond to these values. A mini mowing unit comprising TTZ-30C and КОС-2,1 is being proposed for operating on smaller farming land plots. The methodologies suggested in this study can be used to justify parameters using identical technical means.
